I think a lot of the more recent PEPs have been syntactic sugar, hence the pushback. And maybe it is time for Guido to take more of a backseat. I've met him too a couple of times and he is a really nice guy and very smart.

Often the biggest win is using generators (or equivalents) with memory use being Python's biggest challenge.

For those increasing hordes using Python with TensorFlow, et al., it's just noise.
